塔吉克斯坦雅夫奇岭金矿区地球化学特征及找矿前景

Geochemical characteristics and prospecting prospect of yafqiling gold deposit in Tajikistan

本工作区位于南天山褶皱系南西侧的泽拉夫尚-突厥斯坦活动带中的波依马扎尔背斜南翼,周边已有大量大中型金矿,基于见矿找矿思路在本矿区开展了1∶1万岩屑地球化学测量,旨在以圈定Au异常为重点,同时以主成矿元素及主要伴生元素As、W、Sb(中低温元素组合)为主,结合次伴生元素Cu、Pb、Zn、Ag、Sn、Mo、Bi(中高温元素组合)圈定了综合异常区。工作表明金元素异常、砷元素异常和综合异常三个方面结合地层、构造、岩浆岩等地质特征推断出AP1、AP2、AP3为找矿前景最为良好的三个异常区,对下一步的找矿突破工作具有重要指示意义。

The working area is located in the south wing of the boymazar anticline in the zelavshang Turkestan active belt on the south west side of the southern Tianshan fold system.There are a large number of large and medium-sized gold deposits around it.Based on the idea of ore prospecting,a 1∶10000 cuttings geochemical survey has been carried out in the mining area,aiming to focus on the delineation of Au anomalies.At the same time,the main ore-forming elements and the main associated elements as,W,Sb(combination of medium and low temperature elements),combined with the secondary associated elements Cu,Pb Zn,Ag,Sn,Mo and Bi(medium and high temperature element combination)delineate the comprehensive anomaly area.The work shows that AP1,ap2 and AP3 are the three abnormal areas with the best prospecting prospects from the three aspects of gold element anomaly,arsenic element anomaly and comprehensive anomaly combined with the geological characteristics of strata,structures and magmatic rocks,which has important guiding significance for the next step of prospecting breakthrough.
